Expedition 70 was the 70th long-duration expedition to the International Space Station. The expedition began with the departure of Soyuz MS-23 on 27 September 2023 [2] [3] [4] with Danish astronaut Andreas Mogensen taking over the ISS command. It ended with the departure of Soyuz MS-24 on 6 April 2024. [5]

Background, Crew and Events

Initially, the expedition consisted of Andreas and his three SpaceX Crew-7 crewmates, Jasmin Moghbeli, Satoshi Furukawa, and Konstantin Borisov from America, Japan, and Russia respectively, as well as Russian cosmonauts Oleg Kononenko (who later assumed the ISS command) and Nikolai Chub (both on a year long ISS mission), and another American astronaut Loral O'Hara, who launched aboard Soyuz MS-24 on September 15, 2023 and were transferred from Expedition 69 alongside the SpaceX Crew-7 astronauts. [6]

However, even after several months of outfitting EVAs and RTOd heat radiator installation, six months later on 9 October 2023, the Nauka RTOd radiator malfunctioned before active use of Nauka (the purpose of RTOd installation is to radiate heat from Nauka experiments). The malfunction, a leak, rendered the RTOd radiator unusable for Nauka. This is the third ISS radiator leak after Soyuz MS-22 and Progress MS-21 radiator leaks. If a spare RTOd is not available, Nauka experiments will have to rely on Nauka's main launch radiator and the module could never be utilized to its full capacity. [7] [8]

The crew was later replenished by subsequent crew rotation missions in the expedition, SpaceX Crew-8, consisting of American astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, and Russian cosmonaut Alexander Grebenkin, and Soyuz MS-25, consisting of Russian cosmonaut Oleg Novitsky, Belarusian space tourist Marina Vasilevskaya, and American astronaut Tracy Caldwell-Dyson. [5] Originally, the Boeing Starliner Crewed Flight Test was supposed to dock during the expedition. Instead, it was again moved farther down the vehicle schedule to May during Expedition 71. [9] The space station was also visited by a non-expedition crew, Axiom Mission 3, consisting of former NASA astronaut Michael López-Alegría (who previously commanded the station during Expedition 14), Italian astronaut Walter Villadei, ESA Swedish Project astronaut Marcus Wandt, and Turkish astronaut Alper Gezeravcı.

Besides the expedition crew, Crew Dragon visited the station, carrying Axiom Mission 3, consisting of Michael López-Alegría of Axiom Space (formerly NASA), Walter Villadei of the Italian Ministry of Defence, Alper Gezeravcı of the Turkish Space Agency, and Marcus Wandt of the Swedish National Space Agency. [17]

The Soyuz MS-25 vehicle carried expedition member Tracy Caldwell-Dyson and visitors Oleg Novitsky of Roscosmos and Marina Vasilevskaya, a flight attendant trained by the Belarus Space Agency for ISS EP-21. One week after docking, Novitsky and Vasilevskaya returned with expedition member Loral O'Hara on the Soyuz MS-24 vehicle. Meanwhile, Kononenko and Chub, who launched on MS-24, returned on the MS-25 vehicle. [5]

Vehicle manifest

For the first time, during 25 March–6 April 2024, all seven currently active ports of ISS were occupied. [18]
